It's easy to get caught up into thinking you need more, but I recommend trying the Universal R5 or R7 ($29 and $39). They should do just about everything a grandfather-in-law...or a babysitter...or most spouses would want. They don't have a lot of clutter, and they have a well-designed layout for TiVos and cable boxes. Depending on your equipment, you may need another remote that can teach it some discrete codes; but if you can do that, it does a good job of executing macros to change inputs, etc.

But I must warn you: they can be a bit finicky to program, and I've returned a couple due to erratic behavior. I purchased both an R5 and an R7 with the plan to return one or the other. In my 30 day return period, the R5 inexplicably refused to work on two different occasions, and the same thing happened once with the R7. To be safe, I ended up returning both, and I picked up another R7. I just got it all set up, and it has frozen up 3 times in the last two nights (device button stays lit as if it jammed up sending a signal). Removing and reinserting the batteries takes care of it, but needless to say, it's going back. I like it well enough to try another one, but I'd rather not have to go through the effort to program another one.
